Toilet cleaning times

I am sure that we all appreciate the fantastic efforts that the wardens and the club go through to keep the toilets and shower blocks in such fantastic condition. I do however have an issue with the times chosen for closure for cleaning especially on sites with one toilet block. I feel mid afternoon would be much more suitable, I have lost count of the number of times that once we have finished packing up to leave, often hot sweaty, sometimes wet and muddy the toilets are shut for cleaning. I feel sure that its not just my bad timing, or is it?
